Mahua is a derivative of the Glymur SoC. Many interconnect nodes are identical and continue to use Glymur fallback compatibles. Mahua introduces SoC-specific configurations and topologies for several NoC blocks, including CNOC, HSCNOC, PCIe West ANoC/Slave NoCs. This updates the existing Glymur yaml schema to include Mahua-specific compatible strings, using two-cell "fallback" compatibles wherever the hardware is identical with Glymur.
